Plastic or Pvc magnetic stripe card
The process of attaching a Plastic or Pvc magnetic stripe to a plastic Pvc card was invented by International Business Machines under a contract with the United States of America government for a security system by Plastic Pvc Cards. Forrest Parry, an International Business Machines Engineer, had the idea of securing a piece of Plastic Pvc magnetic tape, the predominant storage medium at the time, to a Plastic Pvc card base. He became frustrated because every adhesive he tried produced unacceptable results. The tape strip either warped or its characteristics were affected by the adhesive, rendering the tape strip unusable. After a frustrating day in the laboratory, trying to get the right adhesive, he came home with several pieces of Plastic Pvc magnetic tape and several Plastic Pvc cards. As he walked in the door at home, his wife was ironing and watching TV. She immediately saw the frustration on his face and asked what was wrong. He explained the source of his frustration: inability to get the tape to “stick” to the Plastic or Pvc in a way that would work. She said, “Here, let me try the iron.” She did and the problem was solved. The heat of the iron was just high enough to bond the tape to the card.
There were a number of steps required to convert the Plastic Pvc magnetic striped media into an industry acceptable device. These steps included: 1) Creating the international standards for Plastic Pvc stripe record content, including which information, in what format, and using which defining codes. 2) Field testing the proposed Plastic Pvc device and standards for market acceptance. 3) Developing the Plastic Pvc manufacturing steps needed to mass produce the large number of cards required. 4) Adding Plastic Pvc stripe issue and acceptance capabilities to available equipment. These steps were initially managed by Jerome Svigals of the Advanced Systems Division of IBM, Los Gatos, California from 1966 to 1975.
